Infosys Senior System Engineer interview questions

I had a very worst experienced with Infosys .In the starting only it take too much time for application form filling and other documentations .I waited for almost 5-6 hours for F-F interview my interview .slot was at 1:00PM later on i got frustrated then i went directly to HR at round 5:30 PM and asked her whether their is a panel available for mine skill set or not then she told me to wait for some more time and she will collect the information and will inform me. I waited for 10 mins more then one of the HR came out and she took me to some desk to have F-F interview but she was not even aware about the technology and tools which i have come for the interview ,still i controlled my anger and started explaining her from the starting.It was good F-F interview but worst management i would say. Later on i was asked to go for HR round around 6:30 PM where HR asked me what are your expectations from us I told 30 % then she told me i am not sure whether our management will be able to give you that much hike .OH God after remaining 4 years in one company a person even can't ask for 30% and that too when its gonna to be first switch . AFter 2 days i got Regret letter from Infosys stating that we regret to inform you that we are unable to match your expectations.Out come is total waste of time ,it wiil be more good if you go and enjoy your weekend with family and friends.
